ST. LOUIS -- The Astros and No. 1 Draft pick Delino DeShields Jr. have reached an agreement in principle on a contract, a person close to the negotiations told MLB.com on Tuesday.
The Astros wouldn't confirm the deal, citing team policy of not announcing any deals until a contract has been finalized.
DeShields Jr., the son of former Major Leaguer Delino DeShields, was drafted with the No. 8 overall pick in June's First-Year Player Draft. His father told MLB.com on Monday he planned to sign with the Astros and not attend LSU, where he was offered a baseball scholarship.
DeShields Jr. was drafted as a second baseman out of Woodward Academy in College Park, Ga., where he played the outfield. DeShields Jr., who committed to LSU to play baseball, was the leadoff hitter for his private school and hit .415 and led the team in homers (9), RBIs (40) and stolen bases (29).
Astros activate Blum from disabled list
ST. LOUIS -- Veteran infielder Geoff Blum was activated from the disabled list Tuesday, about a month after he underwent surgery to remove loose bodies from his right elbow. To make room on the roster, infielder Anderson Hernandez was designated for assignment.
Blum, who arrived at Busch Stadium just prior to the game against the Cardinals, was hitting .241 with 14 RBIs through 59 games and hadn't played since July 1 at San Diego. Blum played shortstop in all three Minor League rehab games at Double-A Corpus Christi.
"As of right now, I don't think his elbow is going to enter into it," Astros manager Brad Mills said. "He felt fine and there was no swelling. He's thrown well and everything has gone well. I don't think there's going to be any restrictions at all. Probably at shortstop is where we're going to see him the most, but because he is so versatile he could play any place."
Hernandez, who was claimed off waivers on July 21, was hitting .154 since joining the Astros.
"He did a good job for us, but we needed to make a move and we're looking forward to seeing Blummer," Mills said.
Bourgeois enjoying opportunities
ST. LOUIS -- Jason Bourgeois, who made his ninth start of the season on Tuesday and doubled home a run in his first at-bat, understands the role of a backup player requires being able to take advantage of every opportunity. Bourgeois was hitting .244 prior to Tuesday's game.
"I try not to think about it too much, but I need to," said Bourgeois, who started in center field Tuesday against left-hander Jaime Garcia. "I want to go out there and do well and help the team win. As long as I feel like I did something to put the ballclub in position to win, I'll be happy with that."
Manager Brad Mills likes Bourgeois' tools on the basepaths and in the outfield, where he rivals childhood friend and teammate Michael Bourn as one of the fastest guys on the team. Bourgeois, who was a non-roster invitee to Spring Training, is a Houston native who hopes he's found a home with the Astros.
"This is a business," he said. "I've been through it all when it comes to teams wanting me one minute and having different plans the next year. I'll be ready for it all. I'll go out and play and try to finish the season."
Astros take precautions in heat
ST. LOUIS -- With temperatures looming around 100 degrees for much of Tuesday, the Astros took some precautions by canceling the early batting-practice session that had originally been scheduled.
Manager Brad Mills said the club also allowed players to go into the air-conditioned comfort of the clubhouse after their group's turn in the batting cage on the field during regular BP. He also didn't keep the pitchers in the outfield as long to shag balls.
"We still want to get on the field and run around and get a feel for it and swing the bats," Mills said.
The Astros will have early batting practice Wednesday, though the forecast still calls for scorching temperatures. That's because pitcher Brian Moehler is scheduled to throw a simulated game and will face some hitters.
"We'll deal with the heat as it comes," Mills said.
Right-hander Brian Moehler (groin) will throw a simulated game before Wednesday's game, during which shortstop Tommy Manzella (fractured finger) will take some swings before heading to Houston for X-rays on his fractured thumb. ... Brett Myers will start on normal rest Saturday, which will split left-handers Wandy Rodriguez (Friday) and Wesley Wright (Sunday) in the rotation.
